[SR-Users] app_python module

Hi, I have successfully installed the app_python module for the default example of handler.py .. Now, I need to see the output of handler.py,.. I have following questions: 1- What is the output of this module ? does it prints the specific message information extracted from SIP message ? 2- How to write modparam and python_exec in configuration file ? I have tried to write modparam("app_python", "mod_init") but, it gives error and says to use mod_register function instead and I don't know more about mod_register function. 3- I have also tried to use python_exec("child_init", 2) , The Kamailio starts successfully.. When, I connect a soft client to Kamailio, then nothing happens ? How to see the output of handler.py script . Any help in this regards shall be really appreciated .. With thanks. Kind Regards, Nasir
